twitter bootstrap - Flexbox wraps last column of the first row in Safari

Question

The last column of the first row is wrapped to the next line when viewing in Safari, and some other iOS based browsers.

Safari:

Chrome / Others:

Code:

.flexthis {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
}


.flexthis .col-md-4 {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
}

<div class="row flexthis">
  <div class="col-md-4 col-sm-6 text-center">
    <div class="product">
      <img src="img.jpg" alt="" class="img-responsive">
      <h3>Name</h3>
      <p>Description</p>
    </div>
  </div>
</div>

Answer 1

Explanation

This happens because Safari treats :before and :after pseudo-elements as if they were real elements. E.g. think about a container with 7 items. If container has :before and :after Safari will position the items like this:

[:before ] [1st-item] [2nd-item]

[3rd-item] [4th-item] [5th-item]

[6th-item] [7th-item] [:after  ]

Solution

As an alternative to the accepted answer I remove :before & :after from flex containers instead of altering the HTML. In your case:

.flexthis.container:before,
.flexthis.container:after,
.flexthis.row:before,
.flexthis.row:after {
   content: normal; // IE doesn't support `initial`
}
